IPC: B05B14/43
Filed: 1976-09-28
Abstract: 1519240 Electrostatic powder-spray booth GEMA AG APPARATEBAU 28 Sept 1976 [29 Sept 1975] 40263/76 Heading B2L An electrostatic powder coating booth comprises a cabin containing an internal compartment 21, a chamber 30 bounding compartment 21 and in communication therewith, a rotatable filter drum 46 arranged in chamber 30, means for subjecting the inside of drum 46 to reduced pressure, a cleaning device including a stationary suction nozzle 49 spanning the filter drum along a surface line thereof, means for rotating drum 46, a suction blower, and means 52 for connecting nozzle 49 to the blower. Coating takes place in compartment 21 and oversprayed powder falls (following arrows 47) between inclined base plates 25 and 26 and passes through opening 29 into chamber 30, where it is entrained upon mesh or woven surface 40 of drum 46 by virtue of reduced pressure therein. The drum rotates as shown and nozzle 49 acts as a vacuum cleaner to remove powder from the drum; this powder is led to a cyclone separator and recovered for re-use Both the drum 46 and opening 29 preferably extend the whole length of cabin space 21. The degree of vacuum (pressure reduction) at nozzle 49 may be 10-20 times that within drum 46.

Title: Improvements in and relating to dispensing continuous web material

Filed: 1958-12-17
Abstract: 938,802. Towel dispensers. HARCRAFT Ltd. Nov. 11, 1959 [Dec. 17, 1958], No. 40715/58. Class 18. Apparatus for dispensing continuous web material is provided with stop means for limiting the extent to which material can be withdrawn manually to obtain a full portion thereof and which stop means can effect a preliminary projection of the material by releasing means, preferably a spring 16b, powered by pulling out the previous portion of the web, said projection being effected through a delivery slot 12a, in the cabinet of the apparatus by an external finger plate 17e. In one embodiment, Fig. 2, a roll R of paper towelling is positioned between plates 11. The web W extends over a roller 15 mounted between the plates 11 and is held in engagement therewith by a resilient leaf 12b mounted on the cover 12. At one end 15a of the roller shaft a disc 15c is rigidly mounted and carries a pin 15d on its face disposed away from the roller. A driving lever 16, pivoted at 16a, engages the pin 15d and its rearward arm is pulled downwardly by a tension spring 16b. A shoulder 17a on a control member 17 normally engages a pin 15e on the disc 15c, directed towards the roller 15, and is maintained in engagement therewith by a leaf spring 17c urging the lower limb of the member 17 clockwise about a pivot 17b. To deliver the towelling the finger plate 17e is depressed and causes the shoulder 17a to become disengaged from the pin 15e. The roller 15 is rotated in an anticlockwise direction, by the action of the spring 16b on the pin 15d through the lever 16, until the spring is subject to minimum stress and the roller 15 is in a stable position, Fig. 4 (not shown). The projecting part of the towelling is pulled by the user so that the roller 15 is further rotated in an anti-clockwise direction to deliver a further portion of towelling. At the completion of a single rotation of the roller 15 the pin 15e engages the shoulder 17a which has returned automatically to the position shown in Fig. 2. This causes the spring 16b to be extended and therefore reloaded for the next preliminary projection. A cutting edge 12c is provided and the finger plate 17e may be separate from the member 17. In an alternative embodiment, Fig. 7, a plate 18 prevents reverse movement of the web. The finger plate 17e is mounted below the delivery slot 12a and engages the member 17 at 17h. The shaft end 15a is supported by a bridge piece 11b in the opening 11a and carries a cam plate 15g having a follower 15d on its outer face. The pin 15e is replaced by a pawl 15f. The cam 15g engages a flange 16c on the triangular lever 16 to determine the stable position reached after the initial projection of the towelling. An opening 12d, Fig. 6 (not shown), is provided for manual rotation of roller 15 to load or re-load the spring 16b.

Title: Method and device for testing hermetically enclosed reed contacts
IPC: H01H47/00
Filed: 1975-10-07
Abstract: 1529714 Testing relay contacts PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Oct 1975 [1 Sept 1975] 40988/75 Heading G1U To test the contact resistance of magnetostrictive reed relay, the relay contacts are closed by an energizing D.C. and and A.C. of frequency continuously variable over a range values containing the expected torsional resonant frequency of the reeds is passed through the contacts, the voltage developed thereacross being compared with a reference voltage. To ensure a constant contact pressure for different relays, before conducting each main test, the energizing current is first raised to a level ensuring contact closure, then gradually reduced until the contacts open, that value being stored and then the test is carried out using that value plus a fixed percentage. Details of the power supply for such an arrangement are given in Figs. 6-7 (not shown). The A.C. test signal is supplied by a voltage controlled oscillator Fig. 2 (not shown) whose frequency limits and mean frequency are adjustable for different types of relay. The alternating voltage developed across the contact resistance is sensed by amplifier 71 whose output passes to comparators 73n, 73p, wherein the instantaneous voltage are compared to positive and negative reference levels. If the alternating voltage amplitude exceeds either reference level (or both) driving the alternate half-cycles, the comparator outputs go negative providing a low input to logic 80. This has three control inputs viz. "reset" 83; "test" 81 and "indicate" 85, which are operated by control circuitry (not shown). Lamps 15, 17 indicate acceptance or rejection of the relay. By varying the test signal frequency, the resonant torsional frequency is ensured at some stage, this ensures maximum movement of the reeds, ensuring as wide a "scan" of the reed area as possible.

Filed: 1971-09-03
Abstract: 1327989 Bolting devices ELLENBERGER & POENSGEN GmbH 3 Sept 1971 [10 Sept 1970] 41262/71 Heading E2A The fastening device of bolting the door of a washing machine comprises electrically interconnected first and second heatable bi-metallic strips 12, 13 at least one of the strips being provided with a heating winding, a plunger 25 adapted to be moved into its bolting position by deflection of the first bi-metallic strip 12, a fixe dcontract 19 and a moveable contact 18 adapted to be actuated by the second bimetallic strip 13 to co-operate with the fixed contact to short circuit the or at least one of the heating windings. As shown, the two bimetallic strips are contained in a housing 1 and each is provided with a heating winding 16, 17; the contact 19 is carried by a terminal 7 and the contact 18 is carried by the strip 13 and when the contact 18 engages the contact 19 the two heater windings, which are connected in parallel, are short circuited to allow them to cool down so that the contact 18 disengages from the contact 19 whereby the windings are again energised and an oscillating operational condition develops; but the plunger remains in its bolting position. If the plunger is impeded during its travel to the bolting position, the heating windings are still short circuited since the strip 13 can bend independently of the strip 12 and thus the device cannot over-heat. In a modification, only a single winding is provided on one of the bi-metallic strips but since the bi-metallic strips are connected together the winding heats both. In a further modification, the windings instead of being connected in parallel are connected in series and the fixed and moving contacts are so arranged that the winding 16 on the strip 12 is short circuited in the unoperated condition of the device and this causes rapid heating of the strip 13 and, with it, of the strip 12; the plunger is thus moved to its bolting position and the contacts are separated so that both windings are connected in series whereby thermal over-loading of the device is prevented. In this modification also the bimetallic strip 13 is arranged to close a pair of contacts when the plunger reaches its bolting position and to operate a signal or switch on the motor of a spin dryer; opening contacts can replace the closing contacts if desired.

Lateral pressure may be applied by one or more hydraulically applied rollers 7 as the stainlesssteel strip is drawn through straightening rollers 4 and a brake 5 by rotation of the roll body 1, the outer side of the portion of the strip being elongated more than the inner side resulting in bending of the strip. One end of the strip which is corrugated (10, 11) is welded to a ring (3).
